It is possible to create a multiline Edit field and it is possible to edit a multiline text there.
However, whenever I try to use a PowerShell custom action, say, to parse an XML from that multiline edit, AI_GetMsiProperty returns only the first line of the property, while the installer log shows that the property is full.
A changed value to "a"
Code: Select all
$a = @' a b '@ AI_SetMsiProperty A $a
A changed value to "a
